The electric heating tube is composed of metal tube, spiral resistance wire and crystalline magnesia powder. Electric heating tube products are generally made of high-quality imported stainless steel, imported high-temperature magnesia powder, high-quality electric heating wire and other materials, and other structural parts are made of stainless steel, which has excellent overall performance, ultra long service life and easy maintenance. Electric heating tube is an electrical component that converts electric energy into heat energy. It is easy to use, easy to install and pollution-free. It is widely used in various electric heating occasions.
The precautions for the use and storage of electric heating tubes are explained as follows:
1.The electric heating pipe shall be positioned and fixed, and the effective heating area must be immersed in liquid or metal solid, and empty burning is strictly prohibited. If scale or carbon deposit is found on the surface of the pipe body, it shall be removed and reused in time to avoid affecting the heat dissipation and shortening the service life.
2. When heating fusible metal or solid nitrate, alkali, asphalt, paraffin, etc., the service voltage of the electric heating pipe shall be reduced first, and the rated voltage can be increased only after the medium is melted.
3. The magnesia powder at the outlet end of the electric heating pipe shall be protected from the infiltration of pollutants and moisture in the place of use to prevent the occurrence of electric leakage accidents.
4. When heating air, the elements shall be arranged in a cross and uniform manner, so that the elements have good heat dissipation conditions and the flowing air can be fully heated.
5. Safety measures shall be considered when heating nitrate to prevent explosion accidents.
6. The wiring part of the electric heating pipe shall be placed outside the insulation layer to avoid contact with corrosive and explosive media and water; The lead wire shall be able to bear the temperature and heating load of the wiring part for a long time. Excessive force shall be avoided when the wiring screw is tightened.
7. The electric heating tube shall be stored in a dry place. If the insulation resistance is lower than 1m Ω due to long-term storage, it can be dried in an oven at about 200 ℃, or the voltage can be reduced and heated until the insulation resistance is restored.
